Key takeaways
- A quartz watch battery typically lasts two to five years.

- Have it replaced by a jeweller or watch shop to protect the seals.
One of the best things about a quartz watch is how little attention it needs. The battery runs quietly for years. But one day it will need replacing. Here is what to expect.

How long does a watch battery last?
Most quartz watch batteries last two to five years. How long yours lasts depends on the movement, the battery size and the functions the watch uses. Extra features like a working stopwatch (chronograph) function or a light can use more energy. Not sure if your watch is quartz? Read Automatic vs quartz watch.
Signs the battery is running low
- The seconds hand jumps in steps of two to five seconds instead of one. Many quartz movements do this on purpose to warn you.
- The watch loses time or stops and starts again.
- The watch has stopped completely.
What to do when your watch stops
Take it to a jeweller or watch repair shop for a new battery. They have the right tools to open the case back without scratches and can check that the seals close properly afterwards, which matters for water resistance.
Don't leave a dead battery in the watch for months. Old batteries can leak and damage the movement.
Can I replace a watch battery myself?
It is possible with the right tools, but it is easy to scratch the case or damage the gasket that keeps water out. For most people a jeweller is the safer and quicker choice. Afterwards, give your watch a fresh clean: see How to clean a stainless steel watch.

Never change a battery again?
An automatic watch runs without a battery, powered by the movement of your wrist. Learn more in How to wind an automatic watch.

How much does a watch battery replacement cost?
Prices vary by shop and region. A simple battery change at a jeweller is usually quick and affordable.
Is it bad to leave a dead battery in a watch?
It is best not to. An old battery can leak over time and damage the movement.
